I assume that for your setup the first part of the configure.ac check 
(using `LIBS="-lclangTooling -lclangFrontend -lclangDriver ..."`) used 
to succeed and only now started to fail due to that



/usr/bin/ld: cannot find -lclangSupport: No such file or directory


that should get addressed now as per 
<https://lists.freedesktop.org/archives/libreoffice/2022-August/089214.html>

I noticed 5078591de9a0e65ca560a4f1913e90dfe95f66bf CLANGTOOLLIBS needs 
to include -lclangSupport now


Seeing that that change passed Jenkins, I naively assumed that 
libclangSupport would generally be available with our compiler plugins 
Clang 12.0.1 baseline (even if I myself only checked that change with my 
local LLVM 16 trunk build).


So my naive assumption was apparently wrong, and 
 "-lclangSupport is only 
available since Clang 15" should hopefully fix that.  Sorry for the trouble.

Please look into your config.log, why exactly "checking for clang 
libraries to use" fails for you.



I use:

Debian clang version 14.0.6-2
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

autogen.input contains several entries including:

CC=clang
CXX=clang++

What should I install so autogen.sh doesn't complain?

Julien
